GRATE FoR FURNACES.V

SPECIFICATION .forming` part of Letters Patent No. 724,938, dated. April 7, 1903.

Application iled April 21, 1902. Serial No. 103.955. (No model.)

To all whom t may concern:

Be it known that I, HIRAM EDWARD REED, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsyl- Vania, have invented new and useful Improvements in Grates for Furnaces, of which the following is a specification'.

This invention relates to grates for furnaces; and it consists in certain improvements in the construction thereof, as will be hereinafter fully/described, 'and pointed out in the claim. y

More particularly, the invention relates to that class of grates which are allied to mechanical sfokers, the action of the grate being such as to carry the fuel from the point at which it is fed to the furnace to the point of discharge.

The invention is illustrated as follows:

Figure l shows a transverse section of a fire-box comprising a grate formed according to my invention. Fig. 2 shows a section on the line 2 2 in Fig. l. Fig. 3 shows an en- 'larged section on the line 3 3 in Fig. 4. Fig.

4 shows a side elevation of the grate-bar; Fig. 5, a plan view.

The invention as illustrated is adapted to a boiler-furnace.

A marks the boiler; B, the furnace-cham-v rear portion and the enlarged notch or step c4. The grate-bars are preferably open. One

edge of the grate-bar has the surface c5 and the other edge the point c6.

By reference to Fig. 3 it will be seen that` as the grate-bars are rocked the edge c'i follows the line of the edge c5, so that it maintains a close relation between the, edges throughout the movement of the grate-bar. l

relation between the edges, as described, prevents the dropping of the fuel from the grate.

What I claim as new is- In an inclined grate, a series of grate-bars journaled Vtransversely of the grate, the fuelsupporting surface of each bar being stepped to feed the-fuel forward, and the adjacent surfaces of the grate-bars being non-overi lapping and so formed as to preserve a constant space between the bars during the entire movement thereof in combination with means for working said bars.

In testimony whereof I have hereunto set my hand inthe presence of two subscribing witnesses.
